... Difficult, but not impossible... I was suggesting that supporting MQTT using the ESP in its original "modem" mode would be problematic. I fully accept that it should be possible to write a MicroPython driver to provide a BSD socket to a non-networked client. This would communicate via a UART wi...

...I'm not sure if it is useful to handle such a small delay with asyncio. Fair point. A non-sync send() returns in less than a millisecond. As the ESP-Now docs say, these responses come from very low down in the network stack and don't guarantee the message has been or will ever be received by an ...

OK, so the question is whether anyone has written a MicroPython driver for the GC9A01 display. I'm not aware of one, and a forum search draws a blank. You may have to DIY. This usually involves porting Arduino C code to MicroPython, a task that requires familiarity with low level coding in both lang...

The two V+ pins are connected together so what you're suggesting would work. However that is not how I'd wire it as the current for your peripherals would pass through the Pyboard's PCB traces. If high currents are involved - and you mentioned actuators - this is not a good idea. Better to power the...

I don't really understand what you're doing here, perhaps you could clarify. The purpose of print() and uart.write() are entirely different. This is a session on a Pyboard: >>> from pyb import UART >>> uart = UART(1) >>> uart.write(b'\xff\xfd\x18') 3 >>> uart.write returns 3 because 3 bytes were tra...
